BAST holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: BAST has 339 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 76% of BAST's written reviews are positive against 86% of Charging Time's, so the app with the better star average is not the one people write more warmly about.
BAST ships an update every 2 weeks, Charging Time every 3 weeks. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
